what spark plugs are you using with your current engine setting

[rabbito]

i am using ngk iridium spark plug with minor E85 tuned engine..some are saying how we should use colder spark plugs for turbo or tuned engine etc.
higher octane = colder plugs? opinion on spark plugs?

no. higher compression/cylinder pressure= colder plugs.

I installed a new set of OEM Toyota plugs when I bought my car. plugs don't really have any performance gains until you change something drastically in the engine. if you have a distributor, silver plugs have the least resistance and can give you slightly quicker spark timing, but in a DIS system the computer compensates for the built in resistance of platinum/iridium; if, however, silver is installed it will create a detonation issue because of the lack of resistance.
the advantage comes with a multi-spark system. the only one I have found is okada projects coils, but they are like $900 (but I've heard they work very well)

thank you for the wonderful right up 👍👍
right now i recently got piggyback ecu that tuned E85, ignition and injection(1jz) to the fullest without any internals hitting 7,000rpm..i am flying(only stage 1 point of view) right now haha..one morning when i started my car, i hear slight sewing machine sound..a slight tick that got me a little worried...thats when i read about the colder plugs on E85 with iginition timing thing..

stage 1 meaning for other readers: every bolt on external; intake, header, pulley etc..

T.M. Works also have a lot of ignition products and what I like about them is that upgrades can go in stages. But of course if you are force inducted and want to go for the best then just go Okada!
